چکیده مقاله:

DNA polymerase gene from Thermus aquaticus strain YT1 was amplified using VENTTM DNA po-lymerase and cloned under the control of X.PR promoter and expression was induced by a shift in tern perature. The culture was then sonicated, and after centrifugation the lysate was treated with poly‌ethyleneimine followed by a salting-out step. Finally the protein was precipitated with ammonium sulfate and fractionated by gel filtration. The resulting enzyme preparation was stable and active.

Isolation, characterization, and expression in Escherichia coli of the DNA polymerase gene from Thermus aquaticus.

The thermostable properties of the DNA polymerase activity from Thermus aquaticus (Taq) have contributed greatly to the yield, specificity, automation, and utility of the polymerase chain reaction method for amplifying DNA. We report the cloning and expression of Taq DNA polymerase in Escherichia coli. From a lambda gt11:Taq library we identified a Taq DNA fragment encoding an epitope of Taq DN...

Thermus aquaticus ATCC 33923 amylomaltase gene cloning and expression and enzyme characterization: production of cycloamylose.

The amylomaltase gene of the thermophilic bacterium Thermus aquaticus ATCC 33923 was cloned and sequenced. The open reading frame of this gene consisted of 1,503 nucleotides and encoded a polypeptide that was 500 amino acids long and had a calculated molecular mass of 57,221 Da. The deduced amino acid sequence of the amylomaltase exhibited a high level of homology with the amino acid sequence o...
